Introduction. Synovectomy in children with juvenile rheumatoid arthritis (JRA) and psoriatic arthritis (PSA) is still subject of controversial discussion. Our results of
Diffuse-type Tenosynovial Giant-Cell Tumour (d-TGCT) of large joints is a rare, locally aggressive, soft tissue tumour affecting predominantly the knee. Previously classified as Pigmented Villonodular Synovitis (PVNS), this monoarticular disease arises from the synovial lining and is more common in younger adults. Given the diffuse and aggressive nature of this tumour, local control is often difficult and recurrence rates are high. Current literature is comprised primarily of small, and a few larger but heterogeneous, observational studies. Both arthroscopic and open synovectomy techniques, or combinations thereof, have been described for the treatment of d-TGCT of the knee. There is, however, no consensus on the best approach to minimize recurrence of d-TGCT of the knee. Some limited evidence would suggest that a staged, open anterior and posterior synovectomy might be of benefit in reducing recurrence. To our knowledge, no case series has specifically looked at the recurrence rate of d-TGCT of the knee following a staged, open, posterior and anterior approach. We hypothesized that this approach may provide better recurrence rates as suggested by larger more heterogeneous series. A retrospective review of the local pathology database was performed to identify all cases of d-TGCT or PVNS of the knee treated surgically at our institution over the past 15 years. All cases were treated by a single fellowship-trained orthopaedic oncology surgeon, using a consistent, staged, open, posterior and anterior approach for synovectomy. All cases were confirmed by histopathology and followed-up with regular repeat MRI to monitor for recurrence. Medical records of these patients were reviewed to extract demographic information, as well as outcomes data, specifically recurrence rate and complications. Any adjuvant treatments or subsequent surgical interventions were noted. Twenty-three patients with a minimum follow-up of two years were identified. Mean age was 36.3 at the time of treatment. There were 10 females and 13 males. Mean follow-up was seven and a half years. Fourteen of 23 (60.9%) had no previous treatment. Five of 23 had a previous

Aim The aim of this study was to identify the presentation, management and outcomes this rare disease using the large series of patients treated at our unit. Material and Methods We reviewed the medical records and x-rays of all the patients who were referred – treated for PVNS around the knee joint between 1990 and 2002. Results 42 patients totally were treated or had second opinion for PVNS disease. 37 have been analysed in detail. Their mean age was 33 years old and 11 patients were below 17 years of age. There was a predilection for females with 22 (59.5%) out of 37 patients. There was average 3.3 years period of time with swelling/knee symptoms before diagnosis . The MRI scan was the cornerstone for the patient’s assessment. It has proved useful in recurrent disease and posterior ”Bakers cyst” disease. 2 of the patients had been managed with
Ultrasound screening has shown that the shoulder joint is almost always involved in rheumatoid arthritis. But only few of rheumatoid patients suffering from omarthritis are in considerable pain. Loss of strength and mobility is often compensated by the adjacent joints. Low patients demands, as pain and swelling can be treated often temporarely successfully by corticoid injections and the need of a wide exposure of the shoulder joint when performing an open synovectomy are the reasons of the low rate of synovectomies performed in rheumatoid shoulder joints. The clinical outcome after synovectomies in rheumatoid omarthritis is generally superior to those of knee synovectomies and shows a reliable reduction of pain, swelling and an increase of ROM. The surgical trauma in open synovectomy of the shoulder results in an impairment of the complex muscle co-ordination of the shoulder and a painful long-lasting aftertreatment. This disadvantages can be prevented when using arthroscopic techniques. The advantages of the arthroscopic technique are mostly obvious in the shoulder joint. The reduced surgical trauma of the periarticular tissue leaving the proprioreception intact results in reduced postoperative pain, allowing early mobilisation and shorter rehabilitation. Arthroscopic surgery of the shoulder is performed with the patient in beach- chair position under general anesthesia. We use a standard 5mm arthroscope and a motorised synovial resector. To prevent bleeding it is advantageous to utilise cooled non-ionic irrigation solution with epinephrin in addition pressurised by a roller pump. Synovectomy of the glenohumeral joint and of the subacromial bursa is performed via four portals. Potential hazards like injury to the periarticular vessels and nerves or damage of the joint cartilage especially in stiff shoulders can only be prevented with careful proceeding. Active and passive physiotherapy starts on the first postoperative day. Our first series of 12 shoulder arthroscopies done 1989–1991 was followed 3. 8 years postoperatively. Swelling and pain at rest disappeared rapidly after surgery. Pain during motion took longer to subside. At the end of follow-up patients reported slight pain on motion in five shoulders. Postoperatively all patients reported improvement of pain. There was one recurrence of swelling due to bursitis. In this patient no bursectomy was done during shoulder arthroscopy, which is now done as a routine. There was subjectively and objectively an increase of strength postoperatively. ROM showed immediate postoperative improvement, although a slight reduction was noticed during the follow-up period. In 1990–1999 we performed 52
Pigmented villonodular synovitis is a monoarticular proliferative process most commonly involving the synovium of the knee joint. There is considerable debate with regards to diagnosis and effective treatment. We present our experience of managing PVNS of the knee joint over a 12 year period. Twenty-eight patients were reviewed. MRI was used to establish recurrence in symptomatic patients rather than routine screening and to identify posterior disease prior to surgery. Eight patients had localised disease and were all treated with open synovectomy and excision of the lesion, with no evidence of recurrence. Twenty patients had diffuse disease, eight treated arthroscopically and twelve with open total synovectomy. Nineteen patients (95%) had recurrence on MRI, however, only five (25%) had evidence of clinical recurrence. There were no significant complications following
Introduction The radial nerve is at risk in arthroscopic elbow surgery and there are reports of significant nerve injury, particularly with
Purpose: Posterior arthroscopy is generally performed by alternating visual control using the optic introduced via one of the anterior portals which is slid into the slit via the contralaeral posterior compartment. These two “crossed” posterior portals provide access to the posterior part of the menisci and to the condyle but remain oblique. Any sagittal partition separating the posterior compartments limits visual and instrument access to the posterior part of the articular cavity. The purpose of this work was to describe a novel back-and-forth technique for posterior arthroscopy which allows posterior access to the central pivot. Material and methods: The conventional posteromedial access was used. The optic was introduced to visualise the posterior cruciate ligament and the posterior partition, and when in contact with it, to push it forward. The optic was then replaced by a round-headed instrument to perforate the partition above the posterior cruciate ligament and penetrate into the lateral compartment. The instrument was pushed against the posterolateral wall determining the point of the corresponding portal. A motorised knife was introduced into the end of the canula then brought into the medial compartment. The posterior partition was resected, creating a single posterior space which could be examined under direct visual control. During an anatomy study, we examined the relationship between the noble elements in the popliteal fossa and the different instruments used during this procedure. Fifteen patients with villonodular synovitis underwent exclusively
Total Knee Arthroplasty (TKA) necessitates disruption of well-vascularised tissue during exposure and soft tissue release as well as from the cutting of bone, and thus bleeding into the joint space routinely occurs to some degree following TKA. Defining a complication from bleeding is not necessarily straightforward, but includes 3 different conditions: hemarthrosis, hematoma, and bloody wound drainage. All of these conditions can be seen in the normal postoperative setting, and when mild, may be simply observed. However, persistent swelling resulting in clinical symptoms should be appropriately treated. A hemarthrosis is defined as blood being contained in the knee capsule. Although some bleeding is expected, “excessive” hemarthrosis results in increased pain limiting or difficulty regaining motion. If high levels of fluid pressure are present, rupture of the arthrotomy may occur. A hematoma occurs when intra-articular blood escapes the arthrotomy and drains into the overlying soft tissues. This may occur following performance of a large lateral release or an insufficient arthrotomy closure or simply secondary to a large hemarthrosis under tension. Symptoms include ecchymosis, soft tissue swelling, and potential skin complications. Increased pain and limited range of motion frequently accompany these symptoms. Wound drainage may present as a knee that continues to have bloody or serous drainage that continues long after the first or second dressing change. It is this continued wound drainage that is most worrisome, with increased wound infection rates when prolonged drainage is allowed to persist. While excessive bleeding during the early postoperative period is most common, isolated or recurrent hemarthrosis may occur long after recovery from surgery. The incidence of postoperative hemarthrosis is not well studied, but the need for surgical treatment is uncommon. Recurrent hemarthrosis is also relatively rare after TKA and has been reported at rates between 0.3% and 1.6%. The etiology of this complication can be systemic or local, and initial workup should include coagulation studies to rule out any underlying systemic coagulopathy. Conservative therapy including rest, cooling, and elevation is the preferred treatment for mild cases. If conservative treatment is not successful, or the acute hemarthrosis is clinically tense, interfering with recovery, or threatening wound healing, drainage may be the preferable option. This can be done by opening the arthrotomy in the operating room or through large bore arthroscopy cannulae. Careful attention to debridement of clotted blood must be followed by a meticulous search for potential sources of bleeding which should be managed appropriately. Recurrent hemarthrosis may occur at any time but is not commonly diagnosed until the patient has left the early recovery period. Repeated bleeding episodes may lead to an inflammatory cascade that propagates bleeding events more readily. If coagulation studies are normal, the most common source is the impingement of proliferative synovium or other retained soft tissue between the articulating components of the knee prosthesis. Other causes may be multifactorial and synergistic but are not well understood, making diagnosis and treatment more difficult. If symptoms persist, classical treatment has consisted of open or

Tenosynovial giant cell tumour (TGCT) is a rare benign tumour of the musculoskeletal system. Surgical management is fraught with challenges due to high recurrence rates. The aim of this study was to describe surgical treatment and evaluate surgical outcomes of TGCT at an Australian tertiary referral centre for musculoskeletal tumours and to identify factors affecting recurrence rates. A prospective database of all patients with TGCT surgically managed by two orthopaedic oncology surgeons was reviewed. All cases irrespective of previous treatment were included and patients without follow-up were excluded. Pertinent tumour characteristics and surgical outcomes were collected for analysis.Aims

Purpose: Pigmented Villonodular Synovitis (PVNS) is an uncommon presentation characterised by hyperplastic synovium, bloody effusions and bone erosions. Incompletely resected localised and diffuse lesions have a high recurrence rate. The management of recurrent lesions depends on the expertise of the surgeon and severity of the lesion. The imaging characteristics of PVNS and experience of British knee surgeons in managing these lesions is presented in our study. Methods: A postal questionnaire was sent to 100 knee surgeons of the British Association of Surgeons of the Knee (BASK) with questions relating to their experience in managing localised and recurrent PVNS. The options included either arthroscopic or open synovectomy with or without radiotherapy, radical excision or referral. Results: 74 responses were included in the study. 73 out of the total cohort of 74 surgeons (98.7%) had seen less than 5 presentations in their career. Localised lesions were treated primarily by

Primary synovial chondromatosis (PSC) is a rare benign disorder characterised by development of foci of cartilage in the synovial membrane of the joint, bursa or tendon sheath that was first described by Reichel in 1900. The disorder has traditionally been considered as a metaplastic condition, but was recently assoicated with structural chromosomal abnormalities, suggesting a neoplastic origin. The aim of the present study was to evaluate the clinical, arthroscopic and histopathological aspects of PSC involving both the glenohumeral joint and tendon sheath of the biceps. An 18-year-old, right-hand dominant boy presented with right shoulder pain. There was no history of trauma. Pain began in his shoulder about 1 year prior to his clinical visit. Physical examination revealed an active range of motion of the affected side measuring 90 ° of abduction and 150° of forward flexion; internal rotation to the greater trochanter of the hip and external rotation were slightly limited. Plain radiographs revealed multiple calcific nodules in the right glenohumeral joint, the subcoracoid recess, and anterior to the humeral head. There appeared to be mild degenerative changes in the gleno-humeral joint. Magnetic resonance imaging was performed to assess the location of the loose bodies and evaluate intra-articular degenerative changes. It demonstrated multiple loose bodies within the glenohumeral joint, the proximal tendon sheath of the biceps, and also in the subscapularis bursa. There was irregularity involving the anterior aspect of the humeral head consistent with erosive changes. The patient underwent arthroscopic surgery to remove the loose bodies,
